Hoe many real roots does the quadratic equations x² + √x - 2 = 4 have ?

• Imaginary roots will be in pairs. so real root of degree 2 or degree 4 will also be in a pair.

• x^2 + √x - 2 = 4
  => √x = (6 -x^2)
  
  (6 -x^2) is a downward parabola passing through (-√6,0) & (√6,0) & it will cut the curve √x at only one point.
  
  so, one real root.
